Methods and apparatus for determining, communicating and using information including loading factors which can be used for interference control purposes
First Claim
1. A method of operating a wireless terminal comprising:
- monitoring to detect received broadcast signals communicating at least one uplink loading factor, each broadcast uplink loading factor corresponding to an attachment point;
receiving a first signal from a first attachment point;
performing a first measurement on the received first signal;
receiving a second signal from a second attachment point;
performing a second measurement on the received second signal;
wherein said first and second measurements are signal power measurements;
generating an uplink interference report based on the measurement of the first signal, the measurement of the second signal and a first received uplink loading factor corresponding to said first attachment point, said uplink interference report communicating a ratio of first and second values, said first value being a function of a product of said first loading factor and a result of said first signal measurement and wherein said second value is a function of a result of the second measurement; and
transmitting said generated uplink interference report.

Abstract
A wireless terminal receives and measures broadcast reference signals, e.g., beacon and/or pilot signals, transmitted from a plurality of base station attachment points. The wireless terminal monitors for and attempts to recover broadcast loading factor information corresponding to attachment points. The wireless terminal generates and transmits an interference report to a current attachment point, the report based on the results of a measured received reference signal from the current attachment point, a measured received reference signal from each of one or more different attachment points, and uplink loading factor information. In the absence of a successfully recovered broadcast uplink loading factor corresponding to an attachment point, the wireless terminal uses a default value for that loading factor. Generated interference reports are based on beacon signal measurements and uplink loading factors, pilot signal measurements and uplink loading factors, or a mixture of beacon and pilot signal measurements and uplink loading factors.
